While the Saints’ special-teams captain from 2013 has left in free agency, re-signing talks between Ramon Humber — one of the unit’s other best coverage players — and New Orleans were ongoing Thursday, according to an NFL source.

Two other teams were interested in Humber, a backup linebacker and free agent at the moment, said the source, declining to reveal who the clubs were.

Negotiations are unfolding as special-teams captain Will Herring, also a backup linebacker, came to terms with the Dallas Cowboys on a one-year deal Thursday.

Humber tied for third in solo special-teams tackles (six) last year. He also recovered one onside kick each in a Week 15 loss to St. Louis and in a Week 16 loss to Carolina.

For his efforts, he earned almost 63,000 Pro Bowl fan votes, which was ninth among special teamers. He wasn’t selected for the game, however.

Positioned under inside linebackers Curtis Lofton and David Hawthorne on the depth chart, Humber lined up in some of the Saints’ specialty packages on defense, recording 0.5 sacks and two tackles behind the line of scrimmage. He arrived in New Orleans in 2010 after going to Super Bowl XLIV with the Indianapolis Colts, who lost that game to the Saints.

“We put a lot on his plate,” Saints special teams coach Greg McMahon said when asked about Humber toward the end of the 2013 season. “And we know what we’re going to get in this player — he’s dependable; he makes plays when he needs to make plays, so that’s why we kind of lean on him.”
